Redis

Redis is a high-performance, open-source, in-memory data store used as a database, cache, message broker, and queue. It helps developers build fast and scalable applications by storing data in memory for low-latency access.

This solution supports common Redis workflows including key-value storage, caching, session management, pub/sub messaging, real-time analytics, counters, queues, and high-speed application data processing. It is ideal for web applications, APIs, microservices, DevOps workloads, and cloud-native application environments.

Redis Version: Redis 8.6.3 latest stable version. You can verify the installed version using the command below:

redis-server --version
redis-cli --version
